Going to go look at a 2001 cummins 6 speed with 161,000 miles on it and any help would be greatly appreciated.
I have been reading all night and this morning tying to get up to snuff on the "what to look for and what are the common issues" and it's pretty much info overload.......,
I know that the fuel system is the weak link on these trucks, I asked the current owner about the fuel system and he said he has replaced the lift pump a couple of times in the past, The last time replacing it with a unit that is at 19 psi at idle and 10 psi at W.O.T.

I also seen where you take the oil will cap and look for blow by, is that a reliable way to check?

Also when I asked if it was the dreaded 53 block I was corrected and told that those blocks only have issues when power adders are used and trucks are used for "pulling", but was told it was a 55 block.

This truck is still on original clutch, is that a reliable gauge on how the truck has been treated?? thats alot of miles for a clutch I would think.

Also he said 2 times in its life it threw a "no power" code and it was a plugged sensor or valve or something that instantly gave the truck boost....
said it was gummed up and needed to be cleaned out, anyone ever heard of this issue???

I appreciate anyone who reads this to respond with any suggestions, comments, or answers to my somewhat "noobie" questions, lol.
Looking forward to buying this thing!!!!!!!
